STEAM FEED-WATER TRAP.

SPECIFICATION forming part of Letters Patent No. $13,854:, dated March 17, 1885.

Appcation filed March 28, 1884. (No model.)

,'o @ZZ whom it may concern.'

Be it known that I, HENRY CREAMER, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Steam Feed-Water Traps, of which the followingis a specification.

' The object of my invention is to produce an automatic steam feed-water trap which will operate in any position below or above the boiler, can be used with cold or hot water, and work successfully under varying pressures.

It consists of adouble cylindrical vessel pro-v vided with separate chambers of vdifferent diameters for holding the Water and steam. Into these chambers, working simultaneously, is placed a double piston.

In order to more fully describe my invention, I refer to the accompanying drawings.

Figure l is a sectional elevation on line as x, Fig. 2. Fig. 2 is a plan section on line y y, Fig. 1. Fig. 3 is detached side view ofthe valve-gear, showing the relative position of one valve with the other.

Arepresents a hollow steam cylinder or vessel, to which is attached the water-cylinder B, closed at one end. Into this steam-'cylinder A is tted the pistou G, and into the watercylinder B is tted the piston D. These two pistons are joined together by hollow tube E. These pistons are fitted to their respective part-s in the usual manner.

To the piston C is fastened the exhaustvalve a, which is opened when the said piston reaches the end of the stroke by the stem c coming in contact with the upper ledge, f, of the watercylinder B, and when the said valve is opened it is held in position by the spring g.4

Into the tube or rod E is inserted the stem h of the valve I. .To this stem, at j, is fastcned the float k. The valve I is seated on the bottom of the piston D.

In the rodE, above the piston D, are openings f,`(shown in dotted lines, Fig. 1,) and the object of these holes f is for permitting the water to pass through the piston D into the chamber B. The stem his reducedin size, so as to not'obstruct the openings f. When the valve is open, it is retained in position by pin m, fastened to stem h, and which moves freely up and down in theslot n in one side of the rod E. The pistons O D andthe rod E are counterbalanced by the lever-arm O and weight l?, attached thereto, outside of the said cylinders. This lever-arm O is fulcrumed at o, and'this fulcrum-support consists ot' a hollow shaft, p, to which the arm O is attached, and passing through a stuiiing-boX, o', into the chamber A, and is secured to a short arm, o2. This short arm is provided with a roller, 03, resting against the projecting arm eon the rod E.

On one side ot the rod E is fastened the rib or -feather e3. which moves freely up and down in the no ch e4 in the plate b1", which is fastened to the lower base of cylinder A. The object of this is to prevent the pistons from turning around.

Through the hollow shaft p the valveshat't q passes, to the end of which is secured the arm r, resting on the pin m ofthe valve I, and on the other end, beyond the lever O, is attached the arm g4, (see Fig. 3,) on which there is a counter-weight, g5. e To this arm g is attached the arm gs, which is connected to the steam-valve T and water-valve Il by rod o and w.

The operation is as follows: Vater from the main pipes or condensation from the radiating pipes flows through the valve U into thelower part of the chamber A through the opening f in hollow rod E, tilli'ng the chamber B until it reaches the neat la, when the said Heat lc rises and rotates the arm r sutiicient to allow weight g5 on arm g* to pass' the center, when it will fall by its own gravity, and thereby cause the water-valve U to be closed and the steamvalve T to be opened, and the steam will thus be communicated to the chamber A above the steam-piston, forcing the two pistons downward, and expelling the water from the cha-inber B into the boiler through the pipe w. As the pistons descend 'they rai'se the counterweight I) by aid of arms O o2, rotating on the fulcruin at o. In this case the steam-valve T remains open until the projection c5 on the under side of the steam-piston O engages the arm r and carries it back to its position, as shown in full line, Fig. l, when the steam- ValveT is closed and the water-valveUopened. At the same instant that the steam is shut off the exhaust-Valve a is opened by the stem e coming in contact with the ledge f of cylinder B, allowing the steam to escape below the ypistons C D into the chambers A B. This valve is held open by the spring g until the oounter-weight O brings the piston to the top of the cylinder. In this ,oase the top of the valve a comes in Contact with the cylinderhead a2, and closes the same ready for the next operation.y

What I claim is- 1. In' a steam feed-water trap, the Combination of the pistons C and D, joined together by hollow tube E, which is provided with openings f, with the 4water-cylinder B, the steam-cylinder A, joined as shown, and the valve a, substantially as and for the purpose set forth.

2. In a steam feed-water trap, the combination of the pistons C and D, joined together by hollow tube E, with the lever O, WeightP, hollow shaft p, short arm 02, roller o3, arm e, and cylinders A and B, substantially as and for the ,purpose set forth.

3. In a steam feed-Water trap, the-combination of the ioat 7a with arm 1', weight g, stem h, tube E, valves U and T, and cylinders A and B, substantially as and for the purpose set forth.

4. In a steam feed-water trap constructed as described, the exhaust-Valve a, with stem e, in combination with the piston C, spring e, ledge f, and cylinder B, substantially as and for the purpose set forth.

5. In a steam feed-water trap, the cylinders A B, pistons C D, Valve a, oat k, 4valve I, arms r o2 g4, with weight g5, lever-arm O, with weightp, arms@ w,and valvesT U,all arranged substantially as and for the purpose set forth.
